METHOD OF SETTING BRICK IN KILNS.

SPECIFICATION forming part of Letters Patent No. 484,170, dated October 11, 1892.

Application filed December 23, 1891. Serial No. 416,014:- (No model.)

To all whom it may concern.

Be it known that I, FRANK ALSIP, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented cetrain new and useful Improvements in Methods of Setting Brick in a Kiln, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part hereof, and in which- Figure 1 shows an end view of an arch in a brick-kiln. Fig. 2 is a view of the interior of an arch, showing a portion of one-half or one side of the arch and Fig. 3 shows a plan of the bottom two courses of brick in the piers between the arches.

The object of my invention is to secure the thorough burning of the brick in the piers or lower portion of the kiln.

The nature of myinvention consists in setting the brick in the arches and piers of a brick-kiln so as to cause a large portion of the heat to pass into the body of the piers between the arches and thence upward throng the mass of brick above the piers.

a indicates the arches.

0 indicates flue-spaces between the lower courses of brick.

1 and 4 indicate the vertical tiers of brick forming the side walls of the arches.

2 and 3 indicate the vertical tiers of brick in the interior of the pier between the arches.

In my improved method of setting brick the two lower courses are set so as to leave fluespaces 0 as wide as the thickness of a brick between the.brick, as shown in Figs. 2 and 3. In tiers 1 and 4 the course, next above the fines 0 (third course) is set so that the sides of each brick are respectively over the middle of a space and over the middle of abrick between the spaces, and the courses above that are packed as closely as possible up to the upper partor top of the arch, where the courses should be set rather loosely, so as to allow a sufficicnt amount of draft. The brick in tiers 2 and 3 above the bottom two courses are set very openly, so as to secure a draft from the arch through fines c and upward through tiers 2 and 3 into the body of the kiln. I prefer to set them three on three or three across three, the bricks of one layer or course being crosswise to those of the next course up to the height of the top of the arches. The rest of the kiln is set in the usual manner.

The size or height of the flue-spaces c at the bottom of the arch and the looseness or openness of the setting of the tiers 2 and 3 above the bottom may be varied to suit different conditions and secure the passage of a proper proportion of the heat from the arch through the lines o and upward through the interior of the piers, which is the purpose of my inven tion.

I claim as my invention The herein -described method of setting brick in the arches and piers of a brick-kiln so-as to form spaces or fines c in the bottom courses, the courses forming the side walls of the arches above the courses in which said fines are provided being set as closely as possible, those courses at the top of the arch being set loosely or openly to provide fora proper amount of draft and those courses in the interiorof the piers, as tiers 2 and 3, above the fines c and up to the height of the top of t e arch being set very loosely, so as to allow a sufficient proportion of the heat to escape up through the interior of the piers.

FRANK ALSIP.
